Are square business cards a good idea?

Square cards, most often 2.5 x 2.5 inches, trade the familiarity of the standard rectangle for a shape people remember. They stand out in a stack, but they will not slide into a conventional cardholder or wallet slot, so the decision comes down to what matters more for your goal.

• Strong fit for photographers, designers, artists, and other creative fields where a distinctive presentation reinforces the brand.
• The extra visual weight makes the card harder to ignore on a desk or pinboard.
• The trade-off is storage: they do not fit standard card slots and can get set aside instead of filed.
• Give the layout more margin than you think you need, since a square balances differently than a wide rectangle.
